I have installed WLS 8.1 sp2 as multi server (PIA, PIA1, PIA2) on HPUX 11i,=
All servers including Admin are showing in running mode. But when we do a =
stress test to see whether the load balancing is happening between PIA1 & P=
IA2 it fails as all the load goes to PIA1 and after a limit it show the Out=
ofMemory error for PIA1 which
is not expected as the load should also be shared by PIA2.
Some points for reference :
1) All severs are running on same m/c
2) Admin is on port 9999
3) PIA, PIA1 and PIA2 are on PORT XXXX
however PIA2 listing address is 7001 (default)
4) Default Load Algorithm : Random

I am doing the clustering on same m/c=2E
eux130 is a valid m/c as PIA1 is working
fine on it, Listen Address: 127=2E0=2E0=2E1
is defaulted from installation and I did not change that=2E
However, when I put the IP for eux130
in the Listen Address for PIA2 it gives the below error and PIA2=
did not start=2E

Is something bad in my settings of the cluster?,
would be helpful if you can tell me the steps to setup the=
cluster (for PIA, PIA1 & PIA2) in the same m/c=2E

Your trying to start the same port on the same NIC, which you cannot do unless you create a virtual host. If you have 2 NIC's on this box, then point to the other one, assuming this NIC is accessible like the first one. Here is how to setup a virtual host, which sounds like you need.

Use the Administration Console to define a virtual host.

Create a new Virtual Host.
Expand the Services node in the left pane. The node expands and displays a list of services.
Click the virtual hosts node. If any virtual hosts are defined, the node expands and displays a list of virtual hosts.
Click Create a New Virtual Host in the right pane.
Enter a name to represent this virtual host.
Enter the virtual host names, one per line. Only requests matching one of these virtual host names will be handled by the WebLogic Server instance or cluster targeted by this virtual host.
Click Create.
Define logging and HTTP parameters:
(Optional) Click on the Logging tab and fill in HTTP access log attributes (For more information, see Setting Up HTTP Access Logs.)
Select the HTTP tab and fill in the HTTP Parameters.
Define the servers that will respond to this virtual host.
Select the Targets --> Servers tab. You will see a list of available servers.
Select a server.
Click Apply.
Define the clusters that will respond to this virtual host (optional). You must have previously defined a WebLogic Cluster. For more information, see Using WebLogic Server Clusters.
Select the Targets tab.
Select the Clusters tab. You will see a list of available clusters.
Select a cluster.
Click Apply.
Target Web Applications to the virtual host.
Click the Web Applications node in the left panel.
Select the Web Application you want to target.
Select the Targets tab in the right panel.
Select the Virtual Hosts tab.
Select Virtual Host.
Click Apply.
You must add a line naming the virtual host to the etc/hosts file on your server to ensure that the virtual host name can be resolved.

fine on it, Listen Address: 127.0.0.1
is defaulted from installation and I did not change that.
However, when I put the IP for eux130
in the Listen Address for PIA2 it gives the below error and PIA2 did not start.
